DS90UB954-Q1EVM Quick Start
3.4 MIPI CSI-2 Output Signals
There are two options provided for passing out the deserialized data on the DS90UB954-Q1EVM. The first
is a Samtec QSH-type connector, J24, on the top of the board that can be mated with a matching QTH
type connector. The mating connector part number for the J24 connector is QTH-020-01-H-D-DP-A. On
the bottom of the board is a Samtec QTH-type connector, J26, meant for mating with a TDAx evaluation
kit. The signals to the connectors are the same, including access to I
2
C and other signals including PDB
and GPIO. Only one connector should be used at a time. If the J6 connector on the bottom is to be used,
populate the zero ohm resistors on the bottom of the board which extend the traces to the J26 connector.
There are third party solutions like the HDR-128291-XX breakout board from Samtec which can be used.
The HDR- 128291-XX is a breakout board with a mating connector to J24 or J26, providing access to
each pin through standard SMA male connectors. More info on this breakout board can be obtained from
Samtec website. Another third party option is the ZX100 by Zebax Technologies. More information on this
board can be obtained from Zebax website.

of the board. Do not use J24 and J26 connectors at the same time.
